Patent number: 9931111Abstract: A suturing instrument includes a suturing head that is coupled to the shaft of an elongate body member of the instrument by a connector member which may be biased in either a linear orientation along the longitudinal axis of the shaft or any one of a variety of non-linear orientations with respect to the shaft's longitudinal axis. The connector member can comprise a resilient material such that an external force may be applied to the suturing head and move the suturing head from a biased orientation (e.g., linear) to an unbiased orientation (e.g., non-linear). Once the external force is removed, the resiliency of the connector member allows the suturing head to return from the unbiased orientation to the biased orientation. Therefore, a user may adjust the shape of the instrument by applying or removing an external force on the suturing head.Type: GrantFiled: April 25, 2014Date of Patent: April 3, 2018Assignee: Boston Scientific Scime, Inc.Inventors: Michael S.

Patent number: 9918715Abstract: A long articulating steerable clip applier affixed to a user-operated handle. A surgical jaw assembly is attached to the other end of the clip applier. The clip applier is composed of articulating phalanges that are connected end to end by pivoting links and capable of angulations relative to one another when subjected to a tensile force. Each phalange has opposing s-shaped exterior grooves that form two continuous spiral-shaped channels for holding tension wires once the phalanges are assembled. Multiple tension wires are attached to opposite ends of adjacent phalanges. When each wire is pulled, this tensile force causes the phalanges to pivot at equivalent angles with each other. As each individual phalange pivots by an equivalent angle, the sum of these angles causes the free end of the clip applier to pivot by a large angle or a cascading actuation effect.Type: GrantFiled: July 23, 2014Date of Patent: March 20, 2018Assignee: Conmed CorporationInventor: Pavel Menn

Patent number: 9855143Abstract: Methods and apparatuses for regulating aortic regurgitation are provided. A catheter shaft is advanced through vasculature so that a flexible occluding membrane coupled to the catheter shaft is positioned within the aorta, typically the ascending aorta above the Sinus of Valsalva and coronary ostia. Blood flow in the aorta causes the flexible occluding membrane to alternate between an expanded occluding configuration while in diastole and a collapsed lesser occluding configuration is systole. There flexible occluding membrane thereby acts as a temporary aortic valve. The flexible occluding membrane is generally conical in shape, with the tip of the cone disposed closer to the aorta than the proximal rim. In diastole, blood flow expands the flexible occluding membrane so that the proximal rim apposes the inner wall of the aorta. The flexible occluding membrane will have one or more openings to allow perfusion of the coronary arteries in diastole.Type: GrantFiled: March 29, 2016Date of Patent: January 2, 2018Assignee: HOCOR Cardiovascular Technologies LLCInventor: Paul C. Ho

Patent number: 9833608Abstract: A method for positioning an electrode array of a neuromodulation catheter at a target circumferential position along a posterior wall of a superior vena cava includes advancing the catheter to a target longitudinal position within the superior vena cava, and orienting a marker on the extracorporeal portion of the catheter in a circumferential orientation known to position the array at the target circumferential position along the posterior wall. A method of positioning the array at a target longitudinal position includes advancing the catheter into the superior vena cava and using features of the catheter to detect the location of right atrial tissue, such as by sensing for a P-wave using an electrogram captured using an electrode carried at a distal end of the catheter, or by using such electrodes to capture the atrium using atrial pacing pulses. Once the location of the right atria is determined, the electrode array may be deployed in a position known to be proximal to the atrium.Type: GrantFiled: November 20, 2013Date of Patent: December 5, 2017Assignee: NeuroTronik IP Holding (Jersey) LimitedInventor: Stephen C Masson
